VINFIELD O. GIINCKEL, OF TERRE HAUTE, INDIANA.

BOILER FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 394,569, dated December18, 1888.

l Application filed March 2, 1888. Serial No. 265,901. (No model.)

To all whom it m ay concern.'

Be it known that I, WINEIELD O. GUNCKEL, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,haveinvented certain new and useful Improvements in BoilerFeed-Regulators; and I .do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to regulators which are adapted to keep the waterin a steam-boiler at substantially a uniform level; and it consists inthe novel construction and combination of the parts, as hereinafterfully described and claimed.

In the drawings, Figure l is a vertical section through the regulator.Fig. 2 is a crosssection through the regulating-valve and its cylinder.

A is the pipe through which the feed-water is pumped into the regulator,and B is the pipe through which the water passes from the regulator intothe boiler.

C is the casing of the balanced regulatingvalve D, which works withinthe cylinder E.

F is the casing for the float, and G is a junction-piece connecting thefloat-casing with regulating-valve casing. The cylinder E is providedwith annular orifices e in its sides, and has a flange, e', at the top,which is secured by the bolts e2 between the flanges f and g of thefloat-casing and the junctionpiece, respectively.

H is a safety-valve secured to the inlet-pipe A, and h is theoverflow-pipe. This safetyvalve may be a weighted levervalve, as shown,or it may be a spring-valve of any approved construction used for aboiler safetyvalve.

F is the float, which is a hollow vessel of copper or other thin sheetmetal, and (l is a rod which connects the bottom ot' the float with thetop of the regulating-valve D. A series of holes, d', is provided in thesides of the regulating-valve,whicl1 holes register with the annularorifices e in the cylinder.

I is a pipe which connects the top of the float-casing with thesteam-space of the boiler.

J is a pipe which connects the delivery-pipe B with the water-space ofthe casing C and j is a stop-valve which is ordinarily kept closed, sothat no water passes through the pipe J into the boiler.

The delivery-pipe B is connected to the j unction-piece G above theregulating-valve, and the regulator is placed, with regard to theboiler, so that the lioat is supported in line with the level of thewater in the boiler.

The feed-pump is caused to operate continuously and pumps the waterthrough the pipe A, the annular orifices e, the holes d', thejunction-piece G, and the pipe B into the boiler. As the level of thewater rises in the boiler, it raises the oat and with it the valve D.This closes or partially closes the holes d. The pump continues to forcemore water through the pipe A, and the safety-valve is raised. The waterpasses out by the overflow-pipe 71 and is conducted back into the hotwell of the pump. XV hen the water in the boiler gets low, the valve l)falls and admits more water. through it into the pipe Il. The stop-valvey can be opened, if there should ever be occasion to pump water directinto the boiler,with out passing it through the regulating-valve.

That I claim isl. In a boiler feed-regulator, the combination of abalanced valve working in a cylinder and provided with holes registeringwith orifices in the cylinder, a casing for the said valve and itscylinder, an inlet-pipe for 'the feed-water, a safety-valve connected tothe said pipe, a lioat connected to the regulatingvalve, a casing forthe float connected to the said valve-casing and in communication withthe steam-space of the boiler, and a feed-water delivery-pipe connectedto the regulator on the opposite side of the regulating-valve from theinlet-pipe, substantially as and for the purpose set forth.

2. In a boiler feed-regulator, the combination ot' a balanced valveworking in a cylinder provided with annular orifices which register withholes in the said valve, a casing for the said valve and its cylinder,an inlet-pipe for the feed-water connected to the said casing, asafety-valve connected to the feed-pipe, a float connected to theregulating-valve, a casing for the lioat communicating with thesteam-space of the boiler, a junction connect-ing the float-casing. withthe regulating- IOO valve cylinder, and a delivery-pipe connected to thesaid junction-piece, substantially as and for the purpose set forth.

3. In a boiler feed-regulator, the combination of a balanced Valveprovided with holes and Working in a cylinder having annular oriiicesregistering with said holes, a casing for said valve and its cylinder,an inlet-pipe for the feed-Water, a safety-valve connected to said pipe,a float connected to the regulatingvalve, a casing for the floatcommunicating with the steam-space of the boiler and connected to theregulating-valve casing, a feed- Water delivery-pipe, and a pipeprovided with a stop-valve and connecting the inlet Waterspace with thedelivery, so that water Vmay be pumped direct into the boiler ifdesired, substantially as set forth. y

4. In a boiler feed-regulator, the combination of a balanced valveprovided With holes,

a valve-cylinder having a 'ange at one end and orifices registering withsaid l1oles.a casing inclosing the valve-cylinder, an inletpipeconnected to the said casing, a safetyvalve connected to the inletfpipe,a anged junction-piece bolted to the valve-casing and holding thevalve-cylinder centrally therein, a delivery-pipe connected to thejunctionpieee, a float provided with a rod extending through thejunction-piece and connected to the regulatin g-valve, and a easing forthe iioat connected to the said junction-piece and in communication withthe steam-space of the boiler, substantially as described and shown.

In testimony whereof I affix my signature in presence of two witnesses.
